How to get a Munny
Munnys are manufactured and distributed by Kid Robot. You can order them direct from kidrobot.com or if you can find a local designer toy retailer you can get one from there.
I ordered mine from Magic Pony here on Toronto.
Munny comes in a variety of sizes and colours. Very recently (January 2008) a 4" version was released, but there is an 8" DIY version and the 18" "Mega" Munny. The prices range from about $10 for the 4" to nearly $300 for the Mega version. I went with the 8" white and GID (Glow in the Dark) versions which set me back about $30 each.
